Abstract

In Linux embedded system, multimedia application is becoming more and more popular based on the ARM process, therefore, it is very urgent that the development of audio and video in one multi-functional player. Using audio and video media library function, IIS interface, DMA control technology and LCD display technology, to development multimedia player function, using Qt complete embedded graphical user interface development so that the system has a good interface. The audio and video data Input/output by the study, using the software decoding, reduces the system development cost, solve the media play the normal player function. The design principle is clear, easy to realize, has a certain practical value.
